The effect of the fine aggregates properties on the compressive strength of concrete was evaluated using the same concrete mix ratio of 11.53 for cement sand coarse aggregates to obtain concrete class 25 nmm 2 at a constant slump of 50 5 mm using the three types of cements 32.5n and fine aggregates from three locations ts, qv and qb while the effect of the cement.
250 kgm3 in combination with portland cement to form a so-called pozzolanic concrete.The fume particles are perfectly spherical in shape and are about 50 to 100 times finer than cement particles 1.Silica fume has been in use in the concrete industry for over 20 years.An indian standard for address authors corrosion protection division,.
Effect of red mud as cement replacement on the properties of concrete jaspal singh1 1 professor, department of civil engineering punjab agricultural university, ludhiana, punjab, india abstract- indian aluminium industry generates significant amount of solid waste such as red mud.Red mud is produced.
Presents the effect of mix proportion and water cement ratio on workability of concrete.Materials and methods materials used in present investigation were tested as per provision laid down in indian standards.Cement in this study, portland pozzolana cement ppc obtained from single batches throughout the investigation was used.
Cement concrete either with the blending component as a part in cement or alternatively as site blended at the ready mix locations, is the option for a durable civil structure.This paper illustrates in some detail, a comparison of the properties of the fly ash based blended cement concrete and ordinary portland cement opc concrete.
Effect of fineness of source material on compressive strength of alkali-activated mortar at 28 days.In general, fillers with particle diameter between 1 m and 10 m react within 1 day and 30 days, respectively in contrast, particle with a size of 50 m does not undergo in full reaction in presence of available water 46.
Cement ordinary portland cement was used because it is easily available in market.The cement was used in measuring whole tests.The specific gravity of cement was 3.13 and the fineness of cement was 4.Coarse aggregate the coarse aggregate was used as natural coarse aggregate.The specific gravity of the coarse aggregate was 2.
Compressive strength of cement mortar was determined on cubes of face 50 cm 2 in area 7.06 cm cubes made with one part of cement and three parts of standard sand confirming to is 4031-1996 by weight and water corresponding to 25 of normal consistency plus 3 of the combined weight of the cement or sand.The mortar was placed in the standard 7.06 cm size moulds and.
Effect of brick kiln dust flyash in cement concrete majid bashir.Indian fly ashes reported that the increase in ground fineness by 52 could increase the strength by 13.Authors also uphold that the study on lime reactivity strength had more cement.
This paper presents the results of the experimental work conducted to study the effect of quarry waste on self-compacting concrete containing binary cementitious blends of fly ash and cement.For this purpose nine trial mixes were prepared, where the percentage replacement of river sand by quarry waste was 0, 10, 20, 30, 40x25, 50x25, 70x25, and 100x25 to study the flowability.
Fineness modulus 1.9194 fineness modulus 0.91 marble slurry is cohesion less.These both of properties allow marble slurry to be used as an ingredient or a filler material to be added to cement mortar.Optimum quantity of marble slurry for same strength as of control for 13 cement mortar.
